What Is Functional Medicine and Can It Help Chronic Illness
If you’ve been living with chronic symptoms, bounced around from specialist to specialist, and told “everything looks normal,” you’re probably exhausted—not just physically, but emotionally. You’ve tried medications, therapy, and cleaned up your diet. And still feel awful.
You’re not alone. Millions of people with chronic symptoms are stuck in a frustrating cycle of symptom suppression, prescription meds, and unanswered questions.
Many people seek functional medicine because conventional care hit a dead end. They’ve been given a diagnosis (or several), told to manage it with medication, left with side effects, and received no resolution to the original issue.
Functional medicine offers something different: real answers.
Instead of asking, “Which pill matches this symptom?” Functional medicine practitioners ask,
“What’s actually driving this dysfunction in the first place?”
Rather than treating symptoms in isolation, functional medicine looks at the body as an interconnected system. Instead of asking, “What diagnosis fits these symptoms?” we ask, “What’s the underlying cause of dysfunction in this person’s body—and how do we reverse it?”
This is root-cause medicine. And it just might be the breakthrough you’ve been searching for.
Functional Medicine Defined
What is functional medicine, and can it help chronic illness? At its core, functional medicine is a patient-centered, science-based approach that focuses on identifying and resolving the underlying imbalances that drive illness. It doesn’t just seek to manage disease—it aims to restore health. Functional medicine recognizes that chronic conditions aren’t random; they’re the result of long-standing dysfunction across key systems in the body.
Functional medicine practitioners typically spend more time with patients than traditional doctors. I spend time gathering a deep understanding of your story, including your full health history, lifestyle, environment, nutrition, mental health, and more. Lab tests—often more advanced than those used in conventional settings—are used to uncover hidden patterns that might otherwise go unnoticed.
One of the key principles of functional medicine is the concept of biochemical individuality, which recognizes that every person has unique genetic and environmental factors that influence their health. By understanding these factors, I develop tailored treatment plans that address the individual needs of each patient.
But this isn’t a “test-and-supplement” approach. The power of functional medicine lies in its ability to create a highly personalized treatment plan that addresses your unique biochemistry, genetics, and life circumstances. It’s precision medicine—not just in theory, but in practice.
Why Functional Medicine Heals Chronic Illness When All Else Fails
Conventional medicine excels in emergencies and acute care, but conventional medicine struggles with the complexity of chronic illness. If you’ve been handed a diagnosis like IBS, chronic fatigue, autoimmune disease, anxiety, PCOS, or fibromyalgia, you may have noticed that treatment options tend to fall into two categories: pharmaceuticals and symptom management.
Functional medicine challenges that model. Instead of asking “How do we quiet this symptom?” we ask “Why is this happening in the first place?”
For example, if you’re dealing with fatigue and brain fog, a conventional doctor might run basic labs and, if they come back normal, send you on your way. A functional medicine practitioner would ask: Are your mitochondria functioning properly? Is your sleep quality disrupted by cortisol dysregulation? Is your gut inflamed or your microbiome imbalanced? Are toxins, like mold or heavy metals, silently stressing your system?
By following the clues and connecting systems—gut, brain, immune, hormonal, metabolic—functional medicine uncovers the real drivers and root causes of your symptoms. It turns the mystery of “why am I like this?” into a solvable puzzle.
Who Benefits from Functional Medicine?
Functional medicine is especially valuable for people struggling with chronic, complex, or “mystery” illnesses. If you’ve seen multiple providers and still don’t feel well—or you’ve been told it’s all in your head—functional medicine can offer a fresh perspective grounded in data and context.
This approach is effective for people with conditions like autoimmune disease, hormone imbalance, digestive disorders, anxiety and depression, metabolic dysfunction, chronic skin issues, unexplained inflammation, and post-viral or environmental illness. But it’s also ideal for anyone seeking optimal wellness or prevention, especially if you have a family history of chronic disease.
Many of my clients are what I call “high-functioning but unwell.” They’re keeping it together on the outside—working, parenting, achieving—but underneath, they’re mentally and physically exhausted. If that sounds like you, know this: your symptoms are real, and there is something driving them. We just need to uncover it.
What Makes Functional Medicine So Unique?
One of the most powerful concepts in functional medicine is biochemical individuality. In other words, no two people present the same way—even if they share the same diagnosis. One person’s anxiety may stem from gut dysbiosis and nutrient deficiencies; another’s may be driven by trauma and mitochondrial burnout. Same label, different root causes. Different solutions.
This is why personalization is at the heart of everything we do. Functional medicine isn’t just about ordering labs—it’s about interpreting labs in the context of your life. Your story becomes the foundation for your healing. This means we can avoid cookie-cutter protocols and instead design a plan that actually fits you—your goals, your body, your bandwidth.
Another major difference? Time. Functional medicine practitioners spend significantly more time with clients than most conventional providers. In my 360° Deep Dive, I take the time to listen, map out your health journey, and collaborate with you to create a strategy that is realistic, actionable, and effective. This deeper level of care is often what unlocks healing that was previously out of reach.
Why My Approach Is Different
Other functional medicine practitioners stop at the physical body. They might run labs and give supplements—but they often miss the mental and emotional dimensions of healing. Other providers do not connect the dots between mental, emotional, and physical health.
That's what makes my approach different: I blend the science of functional medicine with the insight of psychotherapy, so you’re not just working on your body—you’re rewiring your entire system.
My background in integrative psychotherapy allows me to go further.
Because I'm a therapist, I know how to heal:
✔ Trauma and chronic stress → Your nervous system is regulated through therapeutic support
✔ Shame and self-blame → Your emotional patterns are explored, not ignored
✔ Stuck in survival mode → You learn how to shift from coping to healing
I blend root-cause functional medicine with therapeutic insight to address not just the biochemistry of illness, but the psychological patterns that perpetuate it. We look at your nervous system. Your relationship with food and stress. The emotional load you carry and the burnout that’s become your baseline. Because true healing requires more than protocols—it requires resolving the psychological components too.
This whole-person approach is especially valuable for people with overlapping physical and mental health challenges, such as anxiety, OCD, chronic fatigue, digestive issues, or autoimmune flares worsened by stress and trauma. If you’ve ever felt like no one was connecting the dots between your brain and your body—I connect the dots.

Functional Medicine Is the Future of Healthcare
You don’t need another prescription. You need someone to help you find out what’s actually wrong—and how to fix it. That’s what functional medicine is all about. And that’s what I do.
One of the most common things clients say to me is, “Why didn’t anyone ever explain it this way before?”
That’s the power of functional medicine. It doesn’t just treat the problem—it helps you understand it. And when you finally understand what your body has been trying to say, you can stop fighting it—and start healing.
If you're ready to stop managing symptoms and start healing your root cause, personalized expert guidance is waiting for you.
